Escalloped Whitefish with One Egg

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

Assemble

  1. In a baking dish, layer the flaked white fish.

  2. Sprinkle the rolled crackers and chopped parsley over the fish.

  3. Melt the butter and mix in the flour, then add to the dish.

  4. Beat the egg and pour it over the mixture.

  5. Season with pepper and coarse sea salt.

Bake

  1. Bake for 25-30 minutes until golden and set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White fish
Forms the main body of the dish and provides its flaky texture.
Egg
Binds the mixture and sets when baked, holding the dish together.
Rolled crackers
Absorb moisture and add crumbly texture and light browning on top.
Butter
Adds fat for richness and helps the topping brown in the oven.
Flour
Thickens the butter and helps the sauce-like mixture hold together.

The step that matters

Bake until golden and set. Bake until the egg has set and the top is golden; underbaking leaves a loose, wet center, while overbaking dries and toughens the egg.

Swap the parsley

How well each one fits the dish's main ingredients (fish, butter, flour, egg, pepper):

  1. Parsleythe original
  2. Capersfits about as well
  3. Nutmegfits about as well
  4. Tarragonfits less well

Fit is the average pairing score against fish, butter, flour, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
